Abstract

성형공구내에서 관형상 금속 부위로부터 횡단브랜치를 구비한 중공의 몸체를 생산하기 위한 방법은 내부고압성형 기술을 사용한다.A method for producing a hollow body with a transverse branch from a tubular metal portion in a forming tool uses an internal high pressure forming technique.

이 방법은 최대 생산내부압력(Pilmax)보다 더 높은 내부압력에서 플래톤(고압성형중에 브랜치를 지지함)에 의해서 펀치아웃되는 브랜치의 크라운에 제공된다.This method is provided in the crown of the branch punched out by the platone (supporting the branch during high pressure forming) at a higher internal pressure than the maximum production internal pressure (Pilmax).

그 헤드 끝에 있는 플래튼의 끝면은 작동지지면 보다 더 큰 치수이고, 칼라의 작동 지지면 외주에서 둘러싸는 커팅에지를 가지고 있다.The end face of the platen at the end of the head is larger in dimension than the actuation support face and has a cutting edge surrounding the periphery of the actuating support face of the collar.
